JOHN BRIGGS, OF BOSTON, MASSACHUSETTS.

CAR-SEAT.

Specification of Letters Patent No. 9,091, dated July 6, 1852.

T 0 all whom it may concern:

Be it known that I, J OHN BRIGGS, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Railroad-Car Seats, and that the following description, taken in connection with the accompanying drawings, hereinafter referred to, forms a full and exact specification of the same, wherein I have set forth the nature and principles of my said improvements, by which my invent-ion may be distinguished from others of a similar class, together with such parts as I claim and desire to have secured to me by Letters Patent.

The figures of the accompanying plate of drawings represent my inmprovements.

Figure 1 is a plan or top view of my car seat. Fig. 2 is a rear elevation of the same. Fig. 3 is a vertical section of the same taken in the plane of the line A B, Figs. 1 and 2, representing the back of the seat as doubled up, and Fig. 4 is a vertical section taken in the plane of the line C D representing the back of the seat as raised up.

The object of my improvements is to arrange a car seat which shall be so constructed as to admit of being used either as a day seat or as a seat for reposing at night, and at the same time occupy no more room than those which have heretofore been used. These advantages are effected in my improved car seat, the back of which can be placed at any desired angle and by a peculiar arrangement, which will be hereinafter explained, can be folded up so as to be of the same height as those now used or be raised to twice that height if desired, so as to provide a support for the back of the occupant.

a a a in the drawings represents the framework of the chair.

I) Z) is the seat, which can be moved in or out, having a lip 0 for the purpose, which fits in a groove aZ, formed in the framework a a.

The back is composed of two pieces 6 e and f f, and is supported by the arms g, g which turn on centers at h, it. One of these arms rests on the projecting lips or springs 'Z, i, &c., which can be pressed in or out, so that the said arm can rest 011 either of them, by which arrangement the back can be held at any angle, as will readily be understood by inspection of the drawings.

The pieces 6 e f f which constitute the back are connected to each other by the arms In, 7cZ, Z, each of which is hinged to one edge of both the back pieces 6 e and f 7, into a proper groove in which the said arms fit. Vhen the back is folded up as represented in Fig. 4: the pieces a ef f are held together at each edge by the hinged plates m, m and pins 11., n. lVhen the seat is used for reclining, the piece f f is turned up (the bottom plate m being unfastened by turning the pin it) as it turns freely on the hinges of the arms Z0, Z3, Z, Z. The back f f is then rigidly held by the lips 0, 00, 0, which spring into proper grooves made for the purpose in the top and bottom of the piece 6 e. \Vhen the back is reversed, it will readily be seen that the piece f f can be turned up in a similar manner as before, it being only necessary before the back is reversed to detachthe spring lips 0, 0, and fold the back pieces together as shown in Fig. 3.

Having thus described my improvements in car seats I shall state my claim as follows:

l/Vhat I claim as my invention and desire to have secured to me by Letters Patent is- A car seat constructed with a double back which can be folded up or unfolded by means of the hinged arms is, Zc-Z, Z, operating as above set forth, the two pieces which constitute the back, being held together, when open or raised up, by the spring lips 0, 0, substantially as above described.
